Abstract
Electrically parallel but positionally serial, helically wound segments of heating wire in a cable are each controlled by a chip (thermistor) and are connected to the cable proper by wrapping around notches formed in the insulation of the cable proper at first one side and then the other of the cable. The inner and outer-faces of each chip are connected into each segment by direct contact or by leads at spaced points between which the heating wire is severed. An extruded casing is shrunk-fit over the other parts.
